wanting, and the edge of the 2nd segment of the abdomen and the antenn.ne are unicolorous 

 bluish-black in both sexes. The margins of the fore-wings and the band are very broad, the 

 latter at least as broad as it is long ; the hind margin only slightly suffused with yellowish-white. 

 The transparent spaces are small, and the outermost is roundish. Expands nearly three-quarters 

 of an inch. It is found in Europe, south of the Alps, in May, flying over Heliantliemiun vulgare. 



30. 5". ^rifroHS (Zell.). — Brownish-black; the forehead bronzy; the outer transparent space 

 on the fore-wings composed of three cells only ; palpi and front coxae white beneath ; segments 

 4 and 6 of the abdomen bordered with white behind ; thorax with two broad yellow stripes. 

 Expands about three-quarters of an inch. It is not uncommon in Southern Europe, and, 

 according to Berce, it is found flying over flowering Riiinev in the south of France ; but as 

 his description is not sufficiently precise, and his figure differs from Staudihger's description in 

 having three yellow stripes on the thorax, and in other less important particulars, it is somewhat 

 uncertain whether the insect Berce describes as ^rifrons is really that species. 



31. 5. Leucopsiforviis (Esp.). — Brownish-black ; the thorax with three pale ochre-yellow 

 longitudinal stripes, abdomen above with one similar stripe and with white interrupted stripes 

 on the sides and belly, and segments 2 and 4 narrowly bordered with white ; eye-caps dark ; 

 antennae slightly tinged with rusty-yellow. The transparent spaces of the fore-wings are very 

 small, the outermost consisting of three cells only ; hind margins with two yellowish streaks. 

 Expands about three-quarters of an inch. A very local species, only found near Berlin and in 

 Hungary in August and September. The larva lives for one season in the roots of the spurge. 



32. S. Alysoniformis (Herr. Schafif.). — Violet-black ; thorax with three longitudinal stripes, 

 and segments 2, 4, and 6 of the abdomen bordered with yellow behind, both above and below ; 

 no longitudinal transparent space on the fore-wings, and the other spaces very small and often 

 partly covered with yellow scales. Expands a little over half an inch. It inhabits Bulgaria 

 and Asia Minor. 



33. 5". Osmiafonnis (Herr. Schaff.). — Rather stout and compressed ; cinnamon-brown, with a 

 yellow dot at the base of the fore-wings. The band very broad, and the outer transparent space 

 contracted at the sides. Hinder edge of the 4th segment of the abdomen with a whitish belt, 

 which is a little widened in the middle and on the sides ; abdominal tuft yellowish-brown, with 

 some paler hairs. Expands three-quarters of an inch. Inhabits Sicily and Calabria in May and June. 



34. S. Anthraciformis (Ramb.). — Uniform bluish-black, without belts ; the outer transparent 

 area of the fore-wings composed of three cells. E.xpands about three-quarters of an inch. A 

 Corsican insect, and one of the rarest of the genus. 



35. 5. Doryliforniis (Ochs.). — Greenish-black, wings brownish, the outer area of the fore- 

 wings contracted, and segments 2, 4, and 6 of the abdomen very narrowly bordered with white 

 behind. In the male the back of the head, two lines on the thorax, and the hind tibiae are yellow. 

 The anal tuft is yellow in the middle and at the sides, and the abdomen is spotted with yellow. 

 In the female the back of the head, two lines on the thorax, the belts on segments 4 and 6 of 

 the abdomen, and more or less of the abdominal tuft are red. Expands about three-quarters of 

 an inch. It is found in South Europe and North Africa. 



* 36. 5. Chrysidiformis (Esp.). — Body greenish-black ; the face, and the edges of the 4th and 

 6th segments of the abdomen, white ; fore-wings broadly orange-red along the inner margin and 

 before the hind margin ; the transparent spaces small, the outermost almost filled up with orange- 

 red ; hind tibia; reddish-yellow. Expands rather less than 1 inch. It inhabits Southern and 

 Western Europe (including England, where it is a rarity) from May to July. The lar\'a is said to 

 live in the roots ol Arkinisia campestris, Elychrysuiii, and Riuiiex crispus ; and the moth frequents
